Cold Climates!


1.            Select only ONE of the following environmental stresses: (a) heat, (b) high levels of solar radiation, (c) cold, or (d) high altitude. Discuss specifically how this environmental stress negatively impacts the survival of humans by disturbing homeostasis. (5 pts)
The cold can disturb our homeostasis by making us colder than our normal body temperature. During the winter when it is cold, if felt a slight wind or some sort of cold air one fels frozen, when during the summer when feeling this cold air it is refreshing. This is because our body can only adapt to a certain degree and going below that you start to find heat and shiver.
2.            Identify 4 ways in which humans have adapted to this stress, choosing one specific adaptation from each of the different types of adaptations listed above (short term, facultative, developmental and cultural). Include images of the adaptations. (5 pts each/ 20 pts total)
SHORT TERM: When feeling cold one will cover up or blow on their hands a bit of hot air to warm up.
FACULTATIVE: When having to live for a longer period of time in a climate not accustomed to, one has to change their way of thinking and their body will start to adapt to the change for the time being.
DEVELOPMENTAL: The way one develops when living in colder climates is different the one living in a warmer climate. The body will know how to adapt, for example, by conserving more fats in ones body in order to produce more heat for one
CULTURAL: Different cultures learn to survive in the cold by relying on one another for heat. They keep each other warm and it would be difficult to move out of cold climates because they would not be use to it.
3.            What are the benefits of studying human variation from this perspective across environmental clines? Can information from explorations like this be useful to help us in any way? Offer one example of how this information can be used in a productive way. (5 pts)
This information would be very useful to see how different people could adapt to any different environment. We as people tend to not look outside of the box and just focus on our environment. We don’t think of how others adapt, in California we should consider ourselves lucky to have a variety of climates because our bodies could adapt to different climates.
4.How would you use race to understand the variation of the adaptations you listed in #2? Explain why the study of environmental influences on adaptations is a better way to understand human variation than by the use of race. (10 pts)
I don’t think there is a way to use race to understand these adaptations. I believe it could be based on culture more than anything and what and how these cultures will adapt to different environments.

Language...

          For part one I found this experiment a bit hard. I couldn’t help but laugh at seeing the other person’s reaction but it was an interesting assignment. I would always want to just jump in and say something in words but I knew I couldn’t. So keeping quite was hard. It seemed like my partners were getting frustrated to not hear me speaking back to them. They would ask me the question a few times waiting for the answer they wanted, after a while they just didn’t want to speak to me anymore. I would think that the ones communicating verbally would have the advantage. It is easier for the ones speaking verbally to get things done. I can see this difficulty in the hard of hearing and the mute. It must be very difficult for them to get their point across to people and the only way would be writing or just doing things on their own.
            I was not able to do the whole 15 minutes for Part 2. As much as I tried, I would try to not use my hands or facial expressions I would end up finding myself using them. It was difficult to just be a person sitting there as if I didn’t even exist. They found my communication funny because I was expressionless. To them it was like talking to a wall or a doll. I had never really realized how much I use my hands or facial expressions when talking. I feel like in this world we just see speech as something everyone should have, and forget those who are mute or deaf. I now see how important it is to be able to speak and use our expressions. I think there are people that have a difficulty reading body language. Not everyone may take body language the same way. I think it is important to be able to read body language in order to know how a person really feels. If a person says please but has a very strong body language then you may see that person isn’t being sincere. Body language says a lot about you and how you feel. Not sure when body language wouldn’t be used because I feel body language is important to get to know a person.
